DRAFT-EQUALIZING DEVICE.

Specification of Letters Patent.

Application filed July 26, 1909.

Patented July 23,1912. Serial No. 509,735.

To all whom it may concern Be it known that I, JOHN M. I'Vnrcrrr, acitizen of the United States of America, residing at Brainard, in thecounty of Butlcr and State of Nebraska, have invented certain new anduseful Improvements in Draft-Equalizing Devices, of which the followingis a specification.

My invention relates to a draft equalizing device and is particularlyadapted to be used with agricultural implements or the like in which anextreme throw of the equalizer bar is desirable.

The objects of my invention are to provide a simple and eflicienthitching device which provides means for an extreme throw to compensatefor any irregularity in the draft of the machine or. position of thehorses.

Having these and other objects in view, my invention is illustrated inthe accom panying drawings in which:

Figure l is a front end elevation of my hitching device showing theconnections with the equalizer bar. Fig. 2 is a plan view of thehitching device showing the means of attaching it to a twin pole, theframe and also the means of attaching the equalizer bar to the frame.Fig. 8 is a side elevation of my hitching device. Fig. at is a detailof'the links and hitch bars. Fig. 5 is another detail of the equalizerbar.

In the drawings, reference numeral 1 represents a part of the frame orbeam, the ends of which extend laterally on each side of the pole anddownward at an inclination on each side of the pole. The beam 1 isrigidly secured to the pole members 22. One end of the braces 3 and 4are secured to the ends of the beam 1 and the opposite :nds of thebraces are securely bolted to each of the pole members 2-2. Bearings 5and 6 are secured to the bottom of the pole members and also to thebottom of the braces. This construction provides a frame upon which theparts of the hitch bars 7 are pivotally mounted being journaled in thebearings 5 and 6 at their body portions 8 and 9. The free ends of thehitch bars are bent substantially at right angles to the body portions 8and 9, as shown at the points indicated by reference numerals l0l011 and11. Sleeves l2 and 13 are interposed between the pole members 22 and thebraces and bearings as shown in Fig. 2. The body portions 8 and 9 of thehitch bars pass through said sleeves. An equalizing bar let is pivotallyattached to the beam 1 by the bolt 15.

Apertures are provided in each end of the equalizing bar and the hookedportion of one end of the links 16 and 17 inserted therein. The oppositeends of the links are inserted in apertures provided in the turned ends1010 of the hitch bars thereby making a pivotal connection between theequalizing bar and the hitch bars. The ends 18 and 19 of the hitch barshave suitable apertures provided therein for the purpose of providingmeans of hitching thereto but it is obvious that any suitable means canbe used for this purpose.

Having fully described my invention, what I claim and desire to secureby Letters Patent is:

1. The combination of a hitching device and adraftequalizer mounted on aframe, comprising two hitch bars having both ends of each hitch bar bentsubstantially at right angles to the body portion and in a vertical andhorizontal direction with relation to each other, said body portionsbeing journaled on the frame, a vertically operating equalizing barpivotally attached to the frame, and links to connect said equalizingbar to one end of each hitch bar.

2. In a draft equalizer, the combination of a frame comprising two hitchbars having both ends of each hitch bar bent substantially at rightangles to the body portion and in a vertical and horizontal directionwith relation to each other, said hitch bars being mounted on the frameto permit the oscillation of the bent ends of the hitch bars in avertical direction, a vertically operating equalizing bar pivoted to theframe and means to pivotally connect the bent ends of the hitch bars andthe ends of the vertically operating equalizing bar as described and setforth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN M. WRIGHT.
